The 0.378\" (9.60mm) insulation height gives you the clearance to fit a mating receptacle without crowding adjacent components. That latch holds under vibration; you won't see the connector walk loose in a machine that shakes. Mounting flanges on each end let you screw the header to the board or panel for extra mechanical retention. In a harness that sees repeated yanking, those flanges take the shear force off the solder joints and transfer it to the board mount. At 30 µinch gold, the contact interface resists fretting corrosion and maintains stable contact resistance across 500+ mating cycles. Compare this to the tin-plated version of the same header: tin on the mating face is fine for a one-time assembly, but if you're cycling the connector more than 20-30 times or running it in a humid environment, the gold pays for itself in avoided field failures. The 30 µinch thickness is the middle grade — Molex also offers 15 µinch and 50 µinch gold in the Mini-Fit Jr family, so this sits in the sweet spot for general industrial and telecom duty. The base product number is 003929, which covers the Mini-Fit Jr 5569 series headers in this configuration. The full 0039295203 suffix specifies the 20-position, dual-row, right-angle, gold-plated variant with mounting flanges. ## Mates With Mini-Fit Jr Receptacles The receptacle side uses Molex part numbers from the 5557 or 39-01-2xxx series, loaded with 44476-xxxx or equivalent female crimp pins. The header accepts male pins that are crimped to 16-24 AWG wire (depending on the terminal variant). The through-hole solder posts are 0.142\" (3.60mm) long, which gives enough protrusion through a standard 1.6mm PCB for a reliable solder fillet on the bottom side.","metaTitle":"Molex 0039295203 Mini-Fit Jr Header, 20 Pos, 4.20mm","metaDescription":"Molex 0039295203 Mini-Fit Jr 5569 dual-row header, 20 positions, 4.20mm pitch, right-angle through-hole, male pin, shrouded 4-wall, locking ramp, gold plating.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Molex","Style":"Board to Cable/Wire","Series":"Mini-Fit Jr 5569","Package":"Bulk","Features":"Mounting Flange","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"General Purpose, Industrial, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"2","Pitch - Mating":"0.165\\\" (4.20mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Natural","Insulation Height":"0.378\\\" (9.60mm)","Ingress Protection":"-","Base Product Number":"003929","Insulation Material":"Polyamide (PA66), Nylon 6/6","Number of Positions":"20","Row Spacing - Mating":"0.165\\\" (4.20mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.142\\\" (3.60mm)","Current Rating (Amps)":"-","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-2","Contact Finish Thickness - Post":"100.0µin (2.54µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.2500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b0a0aa1c0af129d4584e880e1dc3db44.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pitch of Molex 0039295203?","answer":"The pitch is 4.20mm (0.165\") on both the mating interface and the row spacing."},{"question":"Is the Molex 0039295203 a male or female header?","answer":"It is a male pin header.
